Benefits of technology

The present invention is about a brake hydraulic pressure unit that improves its mounting characteristics on a vehicle. This is achieved by separating the master cylinder from the brake hydraulic pressure unit, which allows for a smaller size of the base body and further variations in mounting forms. This results in improved mounting characteristics of the brake hydraulic pressure unit in a vehicle.

Problems solved by technology

However, a brake hydraulic pressure unit in the related art is still massive in size and is still restricted in a mounting position on an automatic two-wheel vehicle, resulting in poor mounting characteristics.
Moreover, due to a complicated hydraulic pipeline, it is troublesome to perform processing of the hydraulic pipeline.

first embodiment

[0072]As described above, in the brake hydraulic pressure unit 1 according to the present invention, the inlet valve hole 10 and the outlet valve hole 11 are open on the first side face 7 of the base body 6. The master cylinder port 12 and the wheel cylinder port 13 are provided on the second side face 8 of the base body 6. The reservoir port 14 is provided on the third side face 9 of the base body 6. In the base body 6, the first side face 7, the second side face 8, and the third side face 9 are orthogonal and perpendicular to one another. Therefore, in the base body 6, the hydraulic pipeline 20 configuring the hydraulic circuit 30 can be formed in a small region without interference between each of the portions (the pipeline 21 to 28) of the hydraulic pipeline 20. Therefore, the base body 6 can be miniaturized, and thus, the brake hydraulic pressure unit 1 can be miniaturized. Accordingly, a space necessary for mounting the brake hydraulic pressure unit 1 can be minimized and choi...

second embodiment

[0081]Subsequently, the brake hydraulic pressure unit according to the present invention will be described with reference to the drawings.

[0082]In the brake hydraulic pressure unit according to the second embodiment of the present invention, only the structure of the base body is different in contrast to the brake hydraulic pressure unit 1 according to the first embodiment of the present invention. Hereinafter, only the structure of the base body in the brake hydraulic pressure unit according to the second embodiment of the present invention will be described and descriptions regarding the same configuration will be omitted.

[0083]FIG. 5 is a transparent view illustrating another pipeline structure of the hydraulic pipeline inside the base body of the second embodiment of the present invention. FIG. 5(a) is a perspective view illustrating the pipeline structure, FIG. 5(b) is a diagram illustrating the pipeline structure when the base body is seen in the direction horizontal to the se...

Abstract

A brake hydraulic pressure unit 1 includes a housing 2 and a valve case 3. The housing 2 includes a base body 6. The base body 6 includes a first side face 7, a second side face 8, and a third side face 9. The first side face 7, the second side face 8, and the third side face 9 are perpendicular to one another. The base body 6 includes an inlet valve hole 10, an outlet valve hole 11, a master cylinder port 12, a wheel cylinder port 13, and a reservoir port 14. The inlet valve hole 10 and the outlet valve hole 11 are open on the first side face 7. The master cylinder port 12 and the wheel cylinder port 13 are provided on the second side face 8. The reservoir port 14 is provided on the third side face 9.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a brake hydraulic pressure unit, and particularly relates to a brake hydraulic pressure unit used in a brake system including an anti-lock brake system.[0002]In the related art, there is a known automatic two-wheel vehicle equipped with the brake system including the anti-lock brake system (hereinafter, referred to as the ABS). For example, as the brake system in the related art, the ABS including a one channel-type pumpless brake hydraulic pressure unit has been used.[0003]For example, the brake hydraulic pressure unit in the related art includes a metal base body in which a hydraulic pipeline is formed to be provided between a master cylinder and a wheel cylinder port which is connected to a wheel cylinder provided in a brake of a wheel. The base body accommodates the master cylinder, an inlet valve, an outlet valve, and a reservoir. In the base body, the master cylinder, the inlet valve, the outlet valve, the reser...
